3.3.4 Connection of paper-insulated lead-
covered cables up to 70 mm
2
Cu by
means of grease-filled cable boxes
General
Paper-insulated lead-covered cables can be connected to
load-break switch and circuit-breaker panels up to 12 kV
and to load-break switch/fuse panels up to 12 kV. Load-
break switch and circuit-breaker panels are equipped with
a terminal block with locked cable entry ports. The terminal
block has three connection pins moulded into the cast resin
insulation.
On load-break switch/fuse panels, the 12 kV connection
pins are directly below the fuse holders.
Required components (figure 1)

A small cable box (a) for core cross-sectional areas up
to 70 mm
2
or

Two protection covers (c)

Three cable core clamps (d)

One cable block (e)

One hose clip (f)

Polyethylene tape
Procedure
1. Remove the floor plate with the rubber grommet.
2. Cut the cable to the correct length, as shown in
figure 2:

L1 = 515 mm for a small cable box

L1 = 700 mm for a large cable box
R
EMARK
To simplify insertion of the cable cores in the
right tubes of the cable box, it is recommended
to cut the cable cores to different lengths.
3. Finish the cable as shown in figure 2:

L2 = 170 mm for a small cable box

L2 = 200 mm for a large cable box

d = diameter across the lead sheath
Remove the lead sheath over distance (d). Remove the
sharp edges of the lead sheath.
N
OTE
Dimensions L1 and L2 allow for a length of 50
mm for earthing the lead sheath.
